We had a very scary experience on our return journey to the airport. The minibus clearly had a fault with one of the tyres. The driver kept pulling over to the hard shoulder and pulling out again. After about 30 minutes, one of the tyres punctured, at speed, and he had to do an emergency stop on a slip road which was in a very dangerous place. Another passenger spoke to the driver and said that he had told him the tyre was not safe. We were not asked to leave the minibus and had to wait about 10 minutes in a highly unsafe place. The driver did not explain to us what was happening. We were left extremely traumatised by this experience which fell short of what we have come to expect from this service. Passengers lives were put at risk. Please advise me what steps you have taken regarding this incident.
